A thixotropic supramolecular hydrogel of adenine and riboflavin-5'-phosphate sodium salt showing enhanced fluorescence properties.

An equimolar mixture of riboflavin-5′-phosphate sodium salt (RP) and adenine (AD) dissolved in a phosphate buffer (pH 4.0, 1.0% w/v) produces a red coloured transparent thixotropic hydrogel at 30 °C. The gelation of the RPAD system occurs in the pH range of 2–5. FTIR spectra and WAXS patterns indicate self-assembly via H-bonding between the >C=O group of RP… CONTINUE READING
